The composition of the roof structure in the steel structure project, how much is the steel structure per square

It is connected to the top chord node of the roof truss. Steel structure engineering is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts of the steel structure.

The steel structure is widely used in large workshops, stadiums, super high-rises and other fields because of its light weight and simple construction. The steel structure workshop is famous for its few fulcrums, high bearing capacity, many shapes and high technical content. It is not easily affected by structures such as columns and floors, and is strong and firm. Welded steel stairs are famous for their few fulcrums, high bearing capacity, many shapes and high technical content. It is not easily affected by structures such as columns and floors, and is strong and firm. If only natural lighting design is considered, how much per square meter can be used to set the lighting strip steel structure in the roof system.

The roof structure of the steel structure project is composed of roof panels or purlins, roof trusses, skylight frames and roof support systems.. According to the roof material and structure The difference in layout can be divided into:

No purlin purlin roof structure and no purlin structure. When light roofing engineering materials such as color profiled steel plates, asbestos, steel mesh cement cylinder tile roofs, prestressed concrete bricks and concrete roof panels of aerated mixing tanks, the roof structure load can be transferred to the roof truss through some large roof panels. This kind of roof is used It is called a purlinless roof.

Since the span and spacing of the roof trusses are limited by the size of the large roof panel, the span of the roof trusses is generally 3m.. There are 15, 18, 21 ...... 36 meters etc., suitable for asphalt roof truss 6M; the purlin roof slope and span of the roof truss is very flexible, it is more economical to pitch the roof truss 4~9M, how much is the steel structure per square.
